uploaddeamon stopped uploading

Hi,
I can't find a solution for this problem:
Until the 23th of january SBFspot worked perfectly (installed on a Raspberry Pi). Upload every 5 min to PVOutput.
After a apt-get update/apt-get upgrade the deamon is still active but no datapoint are uploaded.
In the log there is only: [20:32:17] INFO: Starting Daemon...
Anybody has a explanation for this?

After installing the Raspberry I created a ram-drive for the temp-files of 1Mb.
Did a Google search on the error and found that my ram-drive was probably to small. Changed the drive from 1Mb to 2Mb an after a restart the uploadDeamon uploaded all the old data to PVOutput.
